Description of activity and work performed
‘Is your Imaging EuroSafe?’ comprises a series of surveys on CT DRLs for different indications.
The 2016 survey campaign was to dedicated the collection of data to calculate DRLs for:
· Acute head trauma CT
· Acute stroke head CT
· Chest CT for pulmonary embolism
· Chest CT: rule out pulmonary metastasis
